EFiGP: Eigen-Fourier Physics-Informed Gaussian Process for Inference of Dynamic Systems
EFiGP: Eigen-Fourier Physics-Informed Gaussian Process for Inference of Dynamic Systems arXiv:2501.14107v1 Announce Type: new Abstract: Parameter estimation and trajectory reconstruction for data-driven dynamical systems governed by ordinary differential equations (ODEs) are essential tasks in fields such as biology, engineering, and physics. These inverse problems — estimating ODE parameters from observational data — are particularly challenging…
